[PATCH] gitlab: force allow use of pip in Cirrus jobs

["Daniel P. Berrangé" <berrange@redhat.com>]

Python is transitioning to a world where you're not allowed to use 'pip
install' outside of a virutal env by default. The rationale is to stop
use of pip clashing with distro provided python packages, which creates
a major headache on distro upgrades.

All our CI environments, however, are 100% disposable so the upgrade
headaches don't exist. Thus we can undo the python defaults to allow
pip to work.

FYI lcitool recently added logic that purges the EXTERNALLY-MANAGED
marker in all the dockerfiles. QEMU will pick that up on the next
refresh, so Linux containers won't have trouble in future.

The macos/FreeBSD build env isn't fully managed by lcitool though,
so we need this manual addition to purge the marker that prevents
use of 'pip'.

This fixes the CI regression that just started hitting on Cirrus
CI macOS images, likely from homebrew python updates.
